Each of us was the grand prize in an ultimate reality competition, the amazing race a sperm makes on the road to fertilization.

To illustrate the full weight of the challenge, Sizing Up Sperm uses real people to represent 250 million sperm on their marathon quest to be first to reach a single egg.
